It was not a deliberate illegal hit. Caldwell had possesion and the job of a safety is to do whatever it takes to get that ball out of there. He was not a poor defensless reciever. He had the ball and made a "football move" oward the endzone. I would agree with you if the ball were overthrown and Kevin still jacks him up like that. Then it would be different.

The NFL rules clearly states that a player cannot hit another player helmet to helmet, I agree though that Caldwell did make a "football move" but a player still can't make that type of hit according to the NFL and that's why a flag was thrown..

I'll go one step further and say that I don't like to see any player get seriously hurt, knock the snot from their nose yes but seeing a player lay on the field for more than a minute is not something any football fan wants to see, so I thought...
